What is "installation art"

n. A genre of art which incorporates any media, including the physical features of the site, to create a conceptual experience in a particular environment.

Installation art is an artistic genre of three-dimensional works that often are site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often called public art, land art or intervention art; however, the boundaries between these terms overlap.
